Transformer Oil Filtration System Introduction

PureTech Transformer Oil Filtration System for High Voltage Substations (Model DVOP) is equipped with a Double-Stage Vacuum Pumping System, which can greatly increase and maintain the vacuum degree inside degassing chamber, thereby effectively reduce the water content, gas content, and achieve a better dielectric strength.

Generally, this Transformer Oil Filtration Plant is suitable for transformer oil processing, Transformer Oil Dehydration, transformer oil degassing, and transformer drying as well. This system is provided with high vacuum pumps (rotary vane vacuum pump and roots booster pump), degassing chamber, oil pump, electrical heater with digital temperature controller, filter cartridges (three-stage filters), PLC and Man Machine Interface, protection settings (overpressure protection, overvoltage protection, phase-lack protection, oil-lack protection, etc.), oil level control, foam control, light and audible alarm, and safety system.

Furthermore, Model DVOP can also be used as an vacuum drying and vacuum filling equipment during transformer maintenance.

Transformer Oil Filtration System Procedure

1. Transformers oil enter into the Oil Purification Machine by the means of pressure difference. transformer oil filtration machine vacuum degassing chamber

2. It will firstly passes through the primary filter which can filter out mechanical particles, and protect the oil pump.

3. Then the oil is being heater by a eletrical heater which has constant temperature controller, thermal vacuum treatment is proved to be the most effective way for oil dehydration and degassing.

4. The heated oil flows into the vacuum chamber where dehydration and degassing happens, the moisture and gas separated from oil will be drained by the vacuum pump or condensed into water stored in the water tank.

5. Transformer oil after dehydration and degassing will be pumped out of the oil purification system after passing through the fine filter which can filter out small impurities, to ensure the cleanliness of oil.

6. This machine can realize inner cycle or external cycle when oil circulation is required.

Transformer Oil Filtration System Processing Data

• Improve transformer oil dielectric strength to above 75 KV. transformer oil filteration machine, oil filter element

• Removal of moisture to below 5 ppm after vacuum dehydration.

• Removal of gases to below 0.1% after vacuum degassing.

• Removal of impurities with multi-stage filtration precision of 1 micron.
